:-/...He's really fucked on the "toss in the cd and reformat" boat guys...
Well first off, Does she need any files at all? (being a coach and all I would think she might need a few) If she does try using a thumb drive to save them. Now I can't be certain they might not get infected but we'll move onto that later.
Now then the CD drive could be dead it self or well the virus has taken control of it. So I assume you have a floppy drive correct? Kill disk should be able to do the job of deleting both of the hard drives memory completely.

Just download it on a non infected computer and follow the instructions on the website to clear off a hard drive (do both hard drives)
Now then you should be set to go ahead and install windows again. If the cd drive wasn't the virus's fault then just grab one at a store (10-30$) or out of a old computer and toss it in there. And from there you should be able to install windows without a hitch (please don't use 98, If you need XP Please pm me and I'll help you from there)
For the thumb drive, Make sure you get a good anti virus installed on the new computer before plugging it into the usb port. Once you get a good anti virus installed I would suggest installing and following these instructions to make sure none of the files she needed were infected by the virus and are hiding in the thumb drive waiting to spread :-/

By the looks of it installed a anti virus, Be it from the net or a thumb drive/external device would probably just be a waste of time. Most advanced virus's/trojans can really just mess up the install/scan of it so really no use :-/
If you have anymore questions feel free to ask. I hope this helps you fix your moms computers. Virus's are never fun.
